1/11. Endocapsular hematoma: report of a case following glaucoma surgery in a pseudophakic eye.The authors describe a case of an endocapsular hematoma that occurred in a 69-year-old pseudophakic diabetic male following mitomycin C (MMC) augmented trabeculectomy for neovascular glaucoma (NVG). The clinical course of the patient is described, and the unique features of this case are presented and discussed. The endocapsular hematoma absorbed in 6 weeks with conservative management. The patient regained the preoperative visual acuity of 20/30, and his intraocular pressure was controlled without any glaucoma medication. The iris neovascularization regressed. This case is the first report of an endocapsular hematoma following glaucoma filtering surgery in a pseudophakic eye with neovascular glaucoma.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
2/11. Bilateral eye hemorrhage after laparoscopic cholecystectomy.A case of bilateral eye hemorrhage after laparoscopic cholecystectomy, probably caused by an increase in venous blood pressure due to carbon dioxide insufflation, is reported.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
3/11. Intraocular hemorrhage after systemic thrombolytic therapy in a patient with exudative macular degeneration.PURPOSE: To report a hemorrhagic complication from thrombolytic therapy in a patient with exudative macular degeneration. CASE REPORT: A 75 year old patient with exudative macular degeneration developed pain and loss of vision in the left eye shortly after receiving tissue plasminogen activator (t-PA) for a myocardial infarction. Examination revealed the patient to be in angle closure. A CT scan revealed the etiology of the angle closure to be a dense vitreous hemorrhage pushing the iris-lens diaphragm forward. intraocular pressure was treated successfully, but the final visual acuity was only light perception. CONCLUSIONS: thrombolytic therapy can lead to devastating intraocular hemorrhages. The presence of exudative macular degeneration may potentially increase the risk of developing such complications.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
4/11. Orbital subperiosteal hemorrhage while scuba diving.PURPOSE: To report an uncommon case of unilateral subperiosteal hemorrhage while scuba diving involving the orbit, a condition characterized by proptosis and associated severe ocular motility disturbances with displacement of the eyeball. MATERIAL AND methods: Observational case report. RESULTS: Unilateral subperiosteal hemorrhage in a 31-year-old woman while scuba diving at a depth of 20 meters. This was documented by clinical and radiographic examination. Computed tomography (CT) scan demonstrated a subperiosteal hemorrhage as a self-limited mass protruding into the left orbit. The process resolved without treatment and without visual or motility sequelae. A CT-scan, nuclear magnetic resonance, and conventional angiography did not show any venous abnormalities in the brain. CONCLUSION: During scuba diving at a depth of 20 meters, the pressure is three atmospheres, whereas within the diving mask the pressure is one atmosphere if it is not equilibrated; thus, a negative pressure is created within the mask. Small vessels can be broken in the conjunctiva or subperiosteal space by this force. It is important to exclude vascular abnormalities, especially if there is a positive family history.- - - - - - - - - - ranking = 3keywords = pressure (Clic here for more details about this article) |
5/11. Causes of subconjunctival hemorrhage.We examined prospectively 8,726 patients in outpatient eye clinics. A total of 225 (2.9%) patients had subconjunctival hemorrhage. No sexual or age predilection was found. The most common causes for the condition were minor local trauma, systemic hypertension, and acute conjunctivitis. Subconjunctival hemorrhages resulting from local trauma were frequent in the summer, and those associated with systemic hypertension were noted most often in older patients. Blood pressures should be examined in patients with subconjunctival hemorrhages, particularly in older patients.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
6/11. Delayed nonexpulsive suprachoroidal hemorrhage after trabeculectomy.Five cases of delayed nonexpulsive suprachoroidal hemorrhage after trabeculectomy in aphakic eyes are reported. Four cases were done under general anesthesia and in three there was straining and bucking at extubation. The most common presentation was sudden severe ocular pain one day postoperatively, associated with marked decrease in vision and low intraocular pressure. The prognosis was related to the extent of the hemorrhage; where suprachoroidal hemorrhage was extensive, surgical drainage appeared to help. Our last two patients, both with massive postoperative nonexpulsive suprachoroidal hemorrhage, underwent surgical drainage of suprachoroidal blood and recovered preoperative visual acuity.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
7/11. Prevention and management of delayed suprachoroidal hemorrhage after filtration surgery.We report two new cases of massive delayed nonexpulsive suprachoroidal hemorrhage (DNSH) following a filtering operation in the aphakic eyes of elderly patients with glaucoma. A timely surgical drainage resulted in full recovery of preoperative visual acuity in both of our patients. As we combine our cases with a series of 18 similar cases of others in the literature, the following conclusions emerge. Limited DNSH does not require surgical intervention for a favorable visual outcome. Massive DNSH, however, requires timely and appropriate surgical intervention to achieve a favorable visual outcome and to avoid persistent hypotony. The most effective surgical intervention is drainage of the suprachoroidal hemorrhage and re-formation of the anterior chamber, but without concomitant vitrectomy. In both limited and massive DNSH, the final visual outcome is not determined by the worst vision at the time of DNSH. Some of the known and suspected risk factors of DNSH following filtering surgery are old age, aphakia, postoperative hypotony, a history of vitreous manipulation or complication, general anesthesia, increased venous pressure, use of fluorouracil, and high myopia. In view of these risk factors, we recommend several preventive measures for decreasing the incidence of DNSH following filtering surgery.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
8/11. Scleral and conjunctival hemorrhages arising from a gunshot wound of the chest: a case report.A young man committed suicide in the back seat of an automobile, witnessed by two law enforcement officers sitting in the front seat who had attempted to dissuade him from killing himself over an eight hour period. death was caused by a contact gunshot wound of the anterior chest, which entered the midsternum and disrupted the anterior right atrium and ventricle of the heart, without involvement of either left ventricle or atrium. At the autopsy, bilateral fresh, confluent scleral and conjunctival sulcus hemorrhages were discovered, with no other evidence of facial or intracranial trauma. These hemorrhages are postulated to have arisen from a sudden pressure wave ascending through the superior vena cava, in a manner similar to the ocular findings associated with the retrograde venous blood flow that occurs during severe thoracic compression. These hemorrhages should not be mistaken for evidence that a decedent was beaten or otherwise involved in an assault episode.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
9/11. Intraocular hemorrhage developing during interferon therapy.A 43-year-old man with chronic active hepatitis c was treated with interferon-beta (IFN-beta) at a dosage of 6 x 10(6) IU/day for a planned 6-week period. Ocular hyperemia, ophthalmalgia, and increased intraocular pressure in the right eye developed 20 days after the start of treatment. intraocular pressure remained high, even after discontinuation of IFN therapy, laser therapy, and iridectomy. Two days later, the right eye was removed because perforation had occurred. The ocular symptoms that developed in this case were thought to have been caused and exacerbated by IFN administration.- - - - - - - - - - ranking = 2keywords = pressure (Clic here for more details about this article) |
10/11. Orbital emphysema as a complication of bungee jumping.Bungee jumping is a dangerous sport with increasing popularity in the western world. We report the case of a 28-yr-old man who sustained an orbital emphysema as a result of bungee jumping. He jumped head first from a 160-ft high bridge over a river. At the end of the jump he dived into the water with his head in a reclined position. The sudden dive into the water caused an increase of the air pressure in the nose and paranasal sinuses, which led to an emphysema of the right orbit resulting from a skull fracture not detectable by x-ray. The patient was treated with oral antibiotics. Five days later, he had no clinical complaints and the ophthalmologic examination was normal. This variation of bungee jumping may bear severe risk factors for health in addition to those known from the classic jumps.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
